FRXCH04	FLNR Heavy Ion Cyclotrons for Investigation in the Field of Condensed Matter Physics Industrial Applications	ion, cyclotron, acceleration, ECR	172
	B. Gikal JINR, Dubna, Moscow Region, Russia
	The cyclotron IC100 of the FLNR JINR provides industrial fabrication of nuclear filters. It is equipped with superconducting ECR-ion source as well as with axial injection system. The specialized beam channel with two coordinates scanning system and equipment for irradiation of polymer films has been installed in the implantation part of the complex. High intensity heavy ion beams of Ne, Ar, Fe,Kr, Xe, I, W have been accelerated up to energy of 1 MeV/nucl. The DC60 cyclotron with smoothly ion energy variation was designed by FLNR for research center at L.N.Gumilev Euroasia State University in Astana. The cyclotron equipped with ECR ion source accelerates ions from Carbon to Xenon. At the Lab of Nuclear Reactions a cyclotron complex for a wide spectrum of applied studies in the field of nanotechnologies has been developed. This complex includes a specialized DC110 cyclotron, which gives high intensity beams of accelerated Ar, Kr, and Xe ions with a fixed energy of 2.5 MeV/nucl. The DC110 cyclotron is in assembling stage now. Cyclotrons U400 and U400M, which are used basically for scientific researches, also are completed with the specialized channels and installations for applied researches. Since 2010 the heavy ion beam lines for SEE testing are used at the U400M and U400 cyclotrons. Ions of O, Ne, Ar, Fe, Kr, Xe, Bi with 3-6 MeV/nucl are available to users.

MOPPA015	Proposal of Laser Ion Beam Accelerator for Inertial Fusion	ion, laser, target, acceleration	272
	F. Scarlat, A.M. Scarisoreanu INFLPR, Bucharest - Magurele, Romania
	The inertial nuclear fusion with laser beams, relativistic electron beams, ion beams, micro-particle beams and superconducting projectiles has been and is investigated analytically and numerically calculated by various authors along years and nowadays. Starting from the record laser peak power of 1.25 PW and radiation peak intensity of 100 EW/square centimeter produced at LLNR using the chirped pulse amplification (CPA) laser technology as well as from ELI Nuclear Physics - laser system, 3 APPOLON 10 PW (150 J/ 15 fs) proposed to be realized, this paper presents the principle and the configuration of a compact ion accelerator with optical laser in an ultra-relativistic regime, for the inertial nuclear fusion. The accelerator operation principle is based on the interaction of a laser beam with plasma. Plasma is an ideal medium for the acceleration of particles because it may stand longitudinal electric fields of high values (several GV/m), approximately three orders of magnitude greater than the ones obtained with RF cavity (limited to 100 MV/m). Plasma allows the conversion of the electromagnetic field of the laser radiation into plasma waves which can capture and accelerate the charged particles. Moreover, the main system parameters of the accelerator are also presented.

MOPPA031	Residual Activity in Heavy-Ion Accelerators as Beam-Loss Limiting Factor	ion, target, proton, accumulation	302
	V. Chetvertkova IAP, Frankfurt am Main, Germany V. Chetvertkova, E. Mustafin, I. Strašík GSI, Darmstadt, Germany
	Residual activity is the main beam-loss limiting factor in high-energy proton accelerators. In order to ensure 'hands-on' maintenance the losses of proton beam should be kept below 1 W/m. It has been shown in our previous publications that the beam-loss criteria for heavy-ion machines may be established by rescaling the '1 W/m criterion' for different heavy ions. For protons the scaling factor is obviously 1. Scaling factors for other ions depend on the charge-mass number of the ion and on the beam energy. For example, for U ions with energy E = 200 MeV/u the scaling factor is 60, i.e. 60 W/m losses of U beam are tolerable from the 'hands-on' maintenance point of view, whereas for U ions with E=1 GeV/u the scaling factor is just 5. In the present paper we show that this scaling factor concept has natural limits of applicability. In the case of very low beam energies or in the case of estimates of long-term accumulated residual activity the tolerable beam-loss criteria cannot be obtained by simple rescaling '1 W/m criterion' with one single number.

	V.A. Bomko, A.P. Kobets, V.V. Panov, K.V. Pavlij, G.V. Sotnikov, B.V. Zajtsev NSC/KIPT, Kharkov, Ukraine
	New pre-stripping section (PSS-20) the MILAC heavy ion linear accelerator with the relation of their mass to charge A/q=20 is developed. That will allow to extend considerably a range accelerating ions and to increase intensity of beams. On an initial part of acceleration of ions from 6 keV/u up to 150 keV/u high capture in process of acceleration of the injected ions is provided interdigital (IH) accelerating structure with Radio-Frequency Quadrupole (RFQ) focusing. On the second part of acceleration of ions from 150 keV/u up to 1 MeV/u the highest rate of acceleration is created interdigital (IH) accelerating structure with drift tubes. Mathematical modeling geometrical and dynamic characteristics of accelerating structures pre-stripping section PSS-20 is executed. Dynamics of heavy ions in the course of acceleration is optimised.

	Development of the automatic control vacuum system (ACVS) for NICA project was beginning. The first step of this work was Nuclotron vacuum system modernization. It were installed new vacuum pumps and gauges with RS-232, RS-485 and ProfiBus interfaces. Devices were combined to the net with central controller at Linac control room. The result of the modernization was creation of remote control, monitoring and automatic protective system. Next step of ACVS creation will be Linac vacuum system automatization. Experience of the Nuclotron vacuum system modernization will be applied for NICA ACVS development.

	A.Y. Orlov, P.N. Alekseev, S.V. Barabin, D.A. Liakin ITEP, Moscow, Russia
	The renovation of the ITEP-TWAC synchronization system is a complex and challenging matter. This system must provide a full-scale timing signal set for all existing and foreseeing modes of operation of the two-ring accelerator facility. Complete design covers all levels of a design hierarchy like decision concerning the new system architecture or basic electronic modules development. In this article we present a description of most important parts of the synchronization system.
